I also thought the "method" of testing nock travel on the two bows was rather "cavemanish" myself. I've never tested for nock travel but my idea would be to put the bow in a drawing devise that would position the low point of the grip against a solid and padded post. I would then have a very straight guide for the "hook" that attaches to the bow string, to follow and inline with the grip post. There would be a winch to pull the bow to full draw and what would determine nock travel would be a lazer secured to the riser of the bow, in line with the grip post and the string hook. When drawn, the lazer would project a point on a distant wall where a travel path of the lazer could be marked during the draw cycle. Different points of grip placement and hook location could be tried to simulate that of where you actually grip the bow and nock the arrow. Since your bow will never be "held" in place at more than one position while shooting, I don't think your nock traveling is the only thing that is "traveling" during the shot. I believe that the riser can "pivot" at your grip point also, reducing some of the effect of a particular bow's poor nock travel. A long stabilizer may actually help to reduce "riser pivot" if infact that this does occur and promote poor nock travel. Just an idea and I'm sure someone can shoot holes in it but be warned,,, it won't bother me HEHE...
